I'm 37 and the .223's and 22-250's are the first rifles I grab.

Hah. You're still a kid.
My favorite is my .257 Roberts. Recoil is minimal but 75g V-MAX work great for p-dogs, coyotes, 100TTSX and 110g AB for antelope, etc. and I load 120g A-Frames during combined deer/elk season. (Haven't pulled the trigger on game with that load but don't doubt it will work.) All the girls love to shoot it and Daughter #1 will be using it for WY antelope come October.
These days I would probably go the .260 route instead.
